Castle Rock does not have a campground except for a primitive camping area accessible only by canoe or boat.
Limited squirrel, turkey and deer hunting are available at the park. For more information, please contact the park office. Check the Hunter Fact Sheets
Fishing and Boating
Along the Rock River, Castle Rock offers 1 1/2 miles of bank fishing. A boat ramp is available for public use, where boat size is limited due to the varying depth of the river. The most commonly caught fish is the catfish, but some bass, northerns, walleye, and crappie may be taken.
Three picnic areas are available for use at Castle Rock, with shelters, picnic tables, playground equipment, grills, toilets and drinking water. Scattered picnic tables are also present along the river. One of the picnic areas offers a beautiful view over the Rock River Valley. Two of the park's shelters may be reserved for a fee (contact the site headquarters).
There are 6 miles of marked hiking trails where hikers can view woodland animals and birds inhabiting the park and photographers can sharpen their skills. Cross-country skiing and tobogganing also are available when weather permits.
